Abstract: Abstract of the Disclosure The pressure regulator includes a valve member which is supported to slide back and forth in a valve housing having a high pressure port, a low pressure port and a bypass port.      Pressure fluid from the high pressure port is bypassed through the valve member via an orifice, a passage and a metering opening formed in the valve member, the passage communicating with a compensating chamber located between the valve member and the valve housing.          As the bypass flow increases, the increased pressure drop across the orifice reduces the pressure in the chamber to compensate for the progressive resistance imposed upon the valve member by a bias spring and by increasing fluid reaction forces. The compensating chamber enables the regulator to maintain a more substantially constant pressure drop across the high and low pressure ports of the regulator at various bypass flow rates.

Abstract: ABSTRACT OF THE DISCLOSURE Upon a call for heat, gas flows to a pilot burner, a spark generating circuit is energized to ignite the pilot burner, and an oscil-lator is energized.  When flame appears, the output signal of the oscillator is effective, through flame responsive means including capacitor means and solid-state switch means, to enable energizing of the primary winding of a coupling transformer at the frequency of the oscillator signal.  When so energized, sufficient power transfer occurs between the primary and secondary windings of the coupling transformer to enable energizing of a relay winding, which energizing terminates energizing of the spark gener-ating circuit and allows gas to flow to the main burner.

Abstract: ABSTRACT OF THE DISCLOSURE           This patent specification describes a technique for protectively coating the electrodes in a plasma patterning device so as to minimize the effect of backscattering of electrode material.            The potentials present in a patterning chamber are such that electrode sputtering material may occur.  If the material of the electrode where the sample is mounted (RIE mode) or the material of the counterelectrode (plasma etch mode) of the reaction chamber is not etchable in the etchant present, electrode material can be sputtered off, backscattered on the polymer surface, and cause incomplete etching.            Polymer films, patterned in fine dimensions by masking and etching, are widely used in microelectronics.  If backscattered material present in the etch area cannot be etched as fast as the polymer film, the back-scattered material on the polymer film surface will cause partial mask-ing and incomplete etching, leaving spikes of polymer.            Coating the electrode with the same polymer,  or with a photoresist or different polymer of corresponding etch rate, precludes such incomplete etching;  the etched hole is very clean, without spikes. The coating on the electrodes may be very thick so as not to require frequent recoating.

Abstract: ABSTRACT OF THE DISCLOSURE   A method and apparatus for pressing plywood is disclosed.  A stack of wood veneer sheets having a layer of adhesive arranged between successive sheets is pressed together between a pair of pressing platens with a given pressure for a first period of time.  The platens are then held in a first relative platen press-ing position for a second period of time.  The first relative position corresponds with the position reached by the pressing platens at the end of the first period of time.  As a result of the pressing method, compression of the wood veneers is minimized, thereby permitting the use of thinner veneers.  A transducer is provided for sensing the first relative pressing position of the platens at the end of the first period of time and for producing a signal during the second period of time corresponding with the deviation of the platens from the first relative position.  In response to the deviation signal, the pressing platens are returned to the first position.  In order to enhance the adhesive bond between successive sheets of the stack, heat is applied to the stack during the first and second periods of time.
